William O. Douglas,
Arizona v. California (373 U.S. 546…
“ But if, as the evidence shows, the dependable Lower Basin supply of system waters is only 8,000,000 acre-feet per annum, 2,000,000 of which are in the tributaries, California can look only to 6,000,000 acre-feet in the mainstream. Thus, California will never be entitled to any of the additional Article III (b) waters (500,000 acre-feet) in the Lower Basin system. Those 'surplus' waters would necessarily be in the tributaries, and under the Court's interpretation they belong exclusively to Arizona, § 4 (a) to the contrary notwithstanding. ”
